Abstract
Factorization of string amplitudes is one way of constructing string i nteraction vertices. We show that correlation functions in string theo ry can be conveniently factorized using loop variables representing de lta functionals. We illustrate this construction with some examples wh ere one particle is off-shell. These vertices are ''correct'' in the s ense that they are guaranteed, by construction, to reproduce S-matrix elements when combined with propagators in a well-defined way.
